Coimbatore Metro Rail Project Faces Continued Delays After Project Reports Rejected
Coimbatore's long-standing metro rail aspirations face uncertainty as the Union government has rejected detailed project reports submitted by the Chennai Metro Rail Limited twice in the last two years. The project, first proposed 16 years ago, has seen multiple revisions and government announcements
Key takeaways
- Coimbatore's metro rail project, initiated in 2010, has been repeatedly stalled by the Union government's rejection of project reports.
- Reasons for rejection include minimal projected time savings for commuters and technical challenges related to the city's right of way.
- Despite multiple government announcements and a significant state allocation, the mass transit system remains uncertain.
- The project has undergone several revisions in scope and cost since its inception.
Coimbatore, the second-largest city in Tamil Nadu, continues to await a decision on its proposed metro rail system, a mass rapid transit initiative first conceived 16 years ago. Despite multiple project proposals and government endorsements over the years, the project has been stalled by the rejection of detailed project reports by the Union government.
What Happened
The concept for a metro rail in Coimbatore emerged in 2010 when the Central government planned to introduce such systems in 16 tier-two cities. While an initial proposal for a mono rail was announced in 2011, a survey in 2013 indicated the city's qualification for a metro rail. By 2017, both the state and central governments revived the metro rail proposal, tasking Chennai Metro Rail Limited (CMRL) with preparing a detailed project report (DPR). Initial plans outlined a 39 km metro rail project with elevated corridors at an estimated cost of ₹10,740 crore.
A subsequent CMRL proposal in July 2023 detailed an elevated metro rail project costing ₹9,000 crore, covering 39 km with 32 stations along Sathyamangalam Road and Avinashi Road. This plan included acquiring land for depots and carriageways, with metro trains designed to have three coaches, each capable of carrying 250 people.
Why It Matters
The Union government's rejection of the DPRs, citing technical and practical concerns, has placed the aspirations of Coimbatore's citizens for an improved public transport system in an ambiguous state. The decision hinges on factors like projected time savings for commuters and the feasibility of elevated corridors given the city's existing infrastructure.
Background
The demand for a mass rapid transit system in Coimbatore predates the 2010 central government initiative. The debate initially centered on the choice between a mono rail and a metro rail. The state government allocated ₹6,683 crore in 2021 for the metro rail implementation.
